Os Unit 2 Pdf Typically, processes are fairly heavy (like ms word), while the threads are lighter (like background save option). the table below highlights some of the differences between the two. Emphasise that the process control block contains sufficient information so that it is possible to interrupt a running process and later resume execution as if the interruption had not occurred. Whenever a command is issued in unix linux, it creates starts a new process. for example, pwd when issued which is used to list the current directory location the user is in, a process starts. The os picks the new processes from the secondary memory and put all of them in the main memory. the processes which are ready for the execution and reside in the main memory are called ready state processes.

Many modern operating systems have extended the process concept to allow a process to have multiple threads of execution and thus to perform more than one task at a time. Simple and powerful primitives for process creation and initialization. unix fork creates a child process as (initially) a clone of the parent [linux: fork() implemented by clone() system call]. Key difference between processes and threads is that multiple threads share parts of their state. typically, allow multiple threads to read and write same memory. In the following chapters, we will explore the different types of threads, thread synchronization mechanisms, and how threads are implemented in modern operating systems. a thread is a unit of execution within a process that can be scheduled for execution by the operating system.
